WILLIAM C. METZNER, OF CHICAGO, ILLINOIS.

STOVE-G RATE.

SPECIFICATION forming part of Letters Patent No. 407,787, dated July 30, 1889. Application filed December 19, 1888. Serial No. 294,097. (No model.)

To all whom t may concern:

Be it known that LWILLIAM C. METZNER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stove Grates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. 'Y

My invention relates to stove-grates made of overlapping adjustable sections, whereby the dimensions of the grate may be varied. The grate may be, when complete, a tilting or a reciprocating or an immovable grate. The drawings show it in the iixed and tilting forms.

In the accompanying drawings, Figure lis a bottom View of a tilting grate embodying my invention. Fig. 2 is a bottom view of a fixed form. Fig. 3 is a top view of the sections of the grate shown in Fig. l. Fig. is a section in line z z of Fig. 1, the grate being right side up. Fig. 5 is a section in line y y of Fig. l, the grate being right side up. Fig. 6 is a section in line o@ c of Fig. 2, the grate being right side up. Fig. 7 is a section in line w w of Fig. 2, the grate being right side up.

A A, Figs. 1, 3, and 4f, are the sections` of the grate. Each such section has the longitudinal midrib A. On the outer side of each such midrib there is a series of transverse ribs A2, and on the inner side of such midrib there is a series of longer transverse ribs A2, one standing opposite every alternate rib A2, and the ribs A3 of one section alternating in spacing with those of the other section, as shown in Fig. 3. These ribs A3 are all set downwardly far enough to bring their upper faces even horizontally with the lower faces of the ribs A2 and A. The ribs A3 of one section may therefore extend beneath the midrib A' and ribs A2 of the other section. The said sections may be moved back and forth upon each other for adjustment of the width of the grate, and said sections may be secured together firmly in any manner. In

Figs. l, 4, and 5, at each end ot' the grate, a cap B lies upon the ribs A3 between the midribs A', and a bolt B' passes through said cap and the inner endvof the bar B2, located against the bottom of the ribs A3. The tightening of said bolt binds said cap and bar tightly to the ribs A2 and fixes the sectionsA A to each other, whereby the body of the grate is completed. Said cap may be dispensed with and thc head or the bolt set on the ribs.

The bars B2 may have one or several holes or a continuous slot b2 to receive the bolt B', and the outer end of said bars should terminate in journals B2, by which the grate is supported in the stove, as is well known. Said bars may be moved to and fro on the bolts B' to vary the distance between the journals, in order that the grate may be applied to iirepots of varying lengths. One of said journals is extended and faced to receive a crank, and it may be notched transversely to facilitate its breaking when it is desired to shorten it. To prevent the sections A A from sliding upon each other longitudinally, lugs a a are formed upon the lower face of one or both the midribs A', between the spaces which the ribs A3 are to occupy. This guides the ribs A3 and causes each to lie directly beneath a rib A2. Thus ,the openings through the grate for the passage of air and ashes are not diminished.

To further facilitate the adjustment of the size of the grate, the ends of the ribs A2 and A3 and the midribs A' may be provided with breaking notches a. By breaking along these notches the length and width of the grate may be reduced.

In Figs. 2, 6, and 7, the rear of the grate is supported on two feet, and the front is extended upwardly and rests against the front wall of thc fire-pot.

The cap B and bolt B above mentioned are used in this form of the grate. Said bolt passes through a plate C, from the bottom of which projects a foot C'. Said bolt draws said cap and plate together, and the sections AAare thus bound to each other. Said caps, bolts, and plates may obviously be placed where it is desired to have the feet C. The lower ends Qt' said feet may also be provided with breaking-grooves c'.

IOO

At the front the ribs A2 are extended Jforwardly and inwardly and united by a transverse web d2, and said web is provided with breaking-notches a to correspond with the notches in the midribs A. The curved faceplate D is applied to the innerl face of the y upward extensions of the ribs A2 by means of bolts D', passing through said plate and between'said ribs. Said bolts may be moved up and down between said ribs to raise and lower said plate to it it to the tire-pot. plate may also have breaking-notches d at its ends.

Breaking-grooves have been heretofore used in stove parts; hence I do not lay claim to the same, broadly.

I claim as my invention- 1. In an adjustable stove-grate, the combination of the sections A A, each having on the side adjacent to the other the ribs A3, said ribs ot' each section alternating in spacing with those on the other section and extending beneath the other section, and bolts to secu-re said sections to each other, substantially as shown and described.

2. In an adjustable stove-grate, the combination of the sections A A, each having on the side adjacent to the other the ribs A3, said ribs of one section alternating in spacing with those on the other section and extending beneath the other'section, one or more lugs a, seated on said sections between the ribs A3, and bolts to secure said sections to each other, substantially as shown and described.

3. In an adjustable stove-grate, the combination of the sections A A, each having on the side adjacent to the other the ribs A3, said ribs of one section alternating` in spacing` with those on the other section and extending beneath the other section, bars B2, terminating in journals B3, applied at the ends of said Said' grate, and bolts to secure said bars and said sections to each other, substantially as shown and described.

4. In an adjustable stove-grate, the combination of the sections A A, each having on the side adjacent to the other ribs A3, said ribs of one section alternating in spacing with those on the other section and extending beneath the other section, slotted bars B2, terminating in journals B3, applied at the ends of said grate, and bolts to secure .said bars and said sections to each other, substantially as shown and described.

5. In an adjustable stove-grate, the combination of the sectionsA A, each having on the side adjacent to the other the ribs A3, said ribs of'one section alternating' in spacing with those on the other section and extending beneath the other section, one or more lugs a, seated in said sections between the ribs A3, bars B2, terminating in journals B2, applied at the ends of said grate, and bolts to secure said bars and said sections to each other, substantially as shown and described.

6. In an adjustable stove-grate, the combination of the'sections A A,Yeach having on the side adjacent to the other the ribs A3, said ribs of one section alternating` in spacing with those on the other section and extending beneath the other section, one or more lugs a, seated in said sections between the ribs A3, slotted bars B2, terminating in journals B3, applied at the ends of said grate, and bolts to secure said bars and said sections to each other, substantially as shown and described.

In testimony whereof` I afiiX my signature in presence ot' two witnesses.

VILLIAM C. METZNER.
